由硼砂和硫酸氧钛合成新型硼酸钛

Abstract

Abstract: A new type of titanium borate was synthesized by wet chemistry method with titanyl sulfate and borax as raw materials.The effects of reactant mix ratio，reactant concentration，and reaction time etc.on the synthesis of titanium borate were investigated.The suitable synthetic conditions of titanium borate were obtained，i.e. room temperature，borax solution concentration of 1 mol/L，titanyl sulfate concentration of 0.9 mol/L，n（Ti）∶n（B）=1∶5，and time of 15~20 min.The contents of B₂O₃，TiO₂，and H₂O of the product were determined through chemical analysis，ICP，and TG/DTG，respectively.IR，and Raman spectra of the product showed the BO33- existed in the form of（B₂O₅）4- group.The molecular formula of titanium borate （TiO）2B₂O₅·4H₂O was confirmed by calculation.The purity of titanium borate was 82%.The product was characterized by XRD and SEM，and results showed that titanium borate was block-like amorphous particles with a particle size at 1~10 μm.

Key words: titanium borate, IR, Raman
